Abstract:
Concurrency control in distributed systems
is an important problem for the simultaneous
execution of transaction over a shared database
can create several data integrity and consistency
problem. The distributed system becomes more
and more important and attractive with progress
in the areas of computer network system.
Concurrency control is the activity of coordinating
concurrent accesses to a database in a multiuser
database management system. The main technical
difficulty in attaining this goal is to prevent
database updates performed by one user from
interfering with database retrievals and updates
performed by another. This system presents
concurrency control for online sales system by
using Wait-Die Algorithm.
